Supertech Mini Cooper W11B16A 1.6L S/C Black Nitrided Exhaust Valve - Single (Drop Ship Only)

The black nitrided finish on this Supertech exhaust valve is a notable detail, offering improved surface hardness and wear resistance compared to standard valves. This specific valve is designed for the W11B16A engine found in certain Mini Cooper models, particularly those with a supercharger, and is intended as a replacement for the exhaust valve in that application.

Supertech uses a black nitride treatment, a case hardening process that alters the surface of the steel to make it tougher and more resistant to heat and corrosion. This makes it a solid option when you're rebuilding the top end or replacing worn components in your Mini Cooper's engine. Each valve is sold individually, so you can order exactly what you need for your specific repair.
